The Chicago Multiscale Depression Inventory (CMDI) was developed to improve accuracy in measuring depression symptoms in individuals with non-psychiatric medical illness. Earlier psychometric evaluation of the CMDI has emphasized properties of items that measure negative affect and experience. In this study, we provide an initial evaluation of an outcome scale of positive items that are also included within the CMDI but have previously been excluded from calculation of the total score. Psychometric data for the CMDI negative and positive item subscales were determined in healthy adults and patients with multiple sclerosis. Analysis included measurements of factor structure, reliability, and validity in comparison with other established measures of depression and affect. Study findings indicate that in healthy and patient samples, the CMDI Positive scale has very good reliability and validity. The Positive scale score also appears to predict depression symptoms beyond the negative item scale scores. The CMDI Positive scale could be a valuable clinical and research tool. Inclusion of the Positive scale in the CMDI total score appears to improve the measure by further capturing symptoms of affect and experience that are important to diagnosis of depression and are not covered by the negative scales alone.

芝加哥多尺度抑郁量表（CMDI）的开发旨在提高对患有非精神科疾病个体抑郁症状测量的准确性。早期对CMDI的心理测量评估强调了测量消极情绪和体验的项目属性。在本研究中，我们对CMDI中包含的但之前被排除在总分计算之外的积极项目结果量表进行了初步评估。在健康成年人和多发性硬化症患者中确定了CMDI消极和积极项目子量表的心理测量数据。分析包括与其他已确立的抑郁和情绪测量方法相比的因子结构、信度和效度测量。研究结果表明，在健康和患者样本中，CMDI积极量表具有非常好的信度和效度。积极量表得分似乎也能预测超出消极项目量表得分的抑郁症状。CMDI积极量表可能是一种有价值的临床和研究工具。将积极量表纳入CMDI总分似乎通过进一步捕捉对抑郁诊断很重要且仅消极量表未涵盖的情绪和体验症状来改进该测量方法。（《神经心理疾病与治疗》，2016年，第22卷，第76 - 82页）
